Same low protein, less chlorine

I am unreasonably excited that King Arthur Flour is coming out with an unbleached cake flour. I love their bread flour, and my entirely-uneducated-bias is against bleached flours. I’m really hopeful that this shows up in my local food store. Sadly, I cannot even find regular cake flour in my local food store, so my hopes are not too high. Anyone who live around me have suggestions of where I can get cake flour around here? My Cake Bible has been pouting at me every time I use regular all-purpose in a birthday cake, but I cannot bring myself to order flour over the internet.
